Summary
Phyllosphere algae diversity in tropical rainforests is influenced by forest type and host trees. Nutrient levels like phosphorus and nitrogen also impact algal communities, particularly green algae orders.
Area of Science:
- Ecology
- Botany
- Microbiology
Background:
- Phyllosphere algae form visible biofilms on plant leaves in tropical rainforests.
- Limited knowledge exists regarding phyllosphere algal diversity and its driving environmental factors.
Purpose of the Study:
- To identify environmental factors influencing phyllosphere algal community composition and diversity in rainforests.
- To characterize microalgal communities on common host trees in different forest types.
Main Methods:
- Utilized single molecule real-time sequencing of full-length 18S rDNA.
- Analyzed phyllosphere microalgal communities on four host tree species across three forest types over four months.
- Investigated environmental factors including nutrient content.
Main Results:
- Green algae orders Watanabeales and Trentepohliales were dominant.
- Algal species richness and biomass were lower in planted forests compared to primeval and reserve rainforests.
- Algal community composition significantly differed between planted and primeval forests and was affected by phosphorus, nitrogen, and ammonium levels.
Conclusions:
- Phyllosphere algal community structure is significantly related to forest type and host tree species.
- This study identifies key environmental factors affecting phyllosphere algal communities, particularly green algae.
- Findings provide a reference for molecular diversity analysis in other algal habitats.

Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Rhizaria are a diverse group of unicellular protists characterized by their threadlike cytoplasmic extensions known as pseudopodia. These structures aid in both locomotion and feeding, giving Rhizaria an amoeboid appearance. Their amoeboid morphology once led to taxonomic confusion, but molecular phylogenetics has clarified their evolutionary placement and emphasized their shared use of pseudopodia despite divergent lineages.This clade comprises diverse lineages such as Chlorarachniophyta,...

The group Stramenopiles include some phototrophic microorganisms. Members of this group possess flagella covered in numerous short, hairlike extensions, a feature that inspired the group's name, derived from the Latin words for "straw" and "hair." Some of the main categories of Stramenopiles include diatoms, golden algae, and brown algae.Diatoms are unicellular, photosynthetic eukaryotes, with over 200 known genera. They play a key role in the planktonic communities of both marine and...

The kingdom Archaeplastida encompasses red and green algae, along with land plants. Unlike other protists with chloroplasts that arose through secondary endosymbiosis, only red and green algae originated from primary endosymbiotic events. This diverse group of eukaryotic organisms contains chlorophyll and performs oxygenic photosynthesis.Algae exist in various forms, from large brown kelp in coastal waters to green scum in puddles and stains on rocks or soil. Some species are responsible for...
